Prerequisite Protocols

Protocols

Tibiofemoral Joint Testing

Primary Conditions

Secondary Conditions

Measurements

Equipment Use Modes

Operating Procedure

Preparation:

The testing procedure assumes that the tibiofemoral joint is prepared according to specimen preparation specifications. See relevant section at ["Specifications/SpecimenPreparation"]

Robot-Specimen Assembly & Alignment:

The testing procedures require placement of the specimen on the robot and following the necessary set-up procedures. These are detailed in the attachment:Infrastructure/ExperimentationMechanics/simVITRO_setup_tutorial.pdf. Specific to this testing protocol:

Coordinate System Optimization:

Preconditioning:

Testing of Primary Conditions:

Patellofemoral Joint Testing

Testing of Primary Conditions:

Post-calibration of pressure sensor:

After completion of testing, remove the pressure sensor and calibrate again to ensure sensor is not damaged. Refer to ["Specifications/PressureCalibration"].

Data Processing

Robotics testing system utilizes "right knee abstraction" for control and data collection. The data, including kinematics-kinetics information and coordinate transformation matrices need to be transformed back to "physical representation" for the left knees for their appropriate description in the physical space.

-- ["aerdemir"] DateTime(2014-05-25T10:44:36Z) Robb, please provide instructions on the process to accomplish this. This may also need to be documented in the joint testing infrastructure page.

Data Storage

All joint testing files, including raw and processed kinematics-kinetics data, coordinate transformation matrices, contact pressure measurements, etc. should be uploaded to the in-house data management system (http://cobicore.lerner.ccf.org/midas, accessible only within the Cleveland Clinic network) for prospective organization (Open Knee(s) Community). Following organization, a documented version of the data will be disseminated at Open Knee(s) project site (https://simtk.org/home/openknee).
